BIG suggestion prewash fabrics with Synthrapol before using them. I did not know about Synthrapol years ago when I made my DD a queen size DWR quilt using greens with a cream center for the rings. I had prewashed all of the fabrics, but did not use anything to set the color. The first time the quilt was washed later some of the greens bled all over the cream. I have tried everything and all suggestions, but to no avail. I was devastated, I was still working at that time and it had taken me about 18 months to make this quilt. The quilt has never been dried in a dryer. I always prewash my fabrics but if it is a color that bleeds, I now use Synthrapol. Good Luck!
